This study analyzes noise levels caused by traffic activities and generator sets (genset) in the Semarang University environment. Measurements were conducted using descriptive analytical methods by comparing measurement results against noise quality standards according to KepmenLH No.48 of 1996. Data collection was carried out in November 2023 at three location points (in front of Building V, Sports Center, and USM gate) during morning (08.00-08.30), afternoon (12.30-13.00), and evening (17.30-18.00) on weekdays and weekends. Measurement results showed traffic noise levels on weekdays reached 88.3 dB in front of the Sports Center, 85.3 dB at Building V, and 82.1 dB at the USM gate. On weekends, the highest noise level reached 82 dB. Generator noise measurements in stationary conditions reached 108.4 dB and increased to 112.4 dB during loading. The highest vehicle volume occurred during weekday evenings, reaching 3,176 vehicles/hour. Research results indicate that noise levels in the campus environment are above the permitted threshold of 55 dB for educational areas. The study recommends the construction of noise barriers and evaluation of generator placement to reduce noise impact on campus activities.

Noise in educational environments can affect the effectiveness of teaching and learning processes. This study aims to analyze the impact of traffic noise on teaching and learning activities in Building V of Semarang University, located along the Soekarno-Hatta arterial road. The research method uses a qualitative descriptive approach by measuring noise levels using a Sound Level Meter on six floors of the building. Measurements were taken during active lecture hours with time intervals of 3 x 30 minutes. The results showed that noise levels on floors 1 to 3 were above the educational environment quality standard of 55 dB according to KepMenLH No. 48 of 1996. Meanwhile, on the 6th floor, the noise level averaged around 55 dB. Excessive noise makes it difficult for students to hear lecturers' explanations, reduces their ability to capture information, and decreases learning material retention. To address these issues, sound insulation installation, spatial planning improvements by designing room layouts farther from noise sources, vegetation planting, and lecture rescheduling to avoid peak traffic times are necessary.
